[s-cars] Boost problem HELP!

[JR]

It wouldn't surprise me it it's getting excessive boost because when it
is working, if it wasn't for the head rest, my head would rip off and
land in the back seat for that first 30 seconds when it's working.  :-P

I know it's not the hose AT the ECU because I tore that up twice now to
make sure I put it back on right when I reinstalled the ECU after it
came back from being upgraded.  So I can find this hose under the hood
or under the carpet/kick panels?  Is it green like it is at the ECU?
